Nice read, thoughtful, and provocative. As a psychiatrist I was interested in his ideas about what bigfoot symbolizes and why people obscess about this myth and the fact that until seeing this creature is a group experience, it will be considered a hallucination or projection. I was not impressed with his arguments about there being plenty to eat for a creature this size as when the author did his walk it was in the height of the berry season which would be gone after the fall. Large mammals like bears eat large amounts then hibernate through the winter while other large mammals like elk, moose, etc. have specialized stomachs to process types of food a hominid could never eat. It's unimaginable that an animal of bigfoots size could make it through a long winter without fire, foodstores, and technology which enabled man to live in these environments. One is then left with the interdimensional travel/UFO connection.... an it's inherent implausibility.
